Information:


Ignition systems can cause electrical shocks. Avoid contacting the ignition system components and wiring.Do not attempt to remove the valve covers when the engine is operating. The transformers are grounded to the valve covers. Personal injury or death may result and the ignition system will be damaged if the valve covers are removed during engine operation. The engine will not operate without the valve covers.
Turn the engine control switch to the OFF/RESET position. Switch the circuit breaker for the engine OFF.
Remove the valve cover of the suspect cylinder.
Pulling on the wiring harness may break the wires. Do not pull on the wiring harness.
Disconnect the ignition harness from the transformer. Remove the transformer from the engine.

(5) Extension
(6) O-ring seal
Inspect the body of the transformer and ground spring (2) for corrosion and/or damage. Verify that screws (1) for the ground spring are secure. Note: Punch through is caused by misfire in the engine that does not generate a diagnostic code.
Check the extension near spacer (3) for signs of punch through (pin holes) and/or arcing.
Inspect O-ring seal (6) inside the extension for damage.
Remove O-ring seal (6). Inspect terminal (4) inside the extension for looseness, corrosion, and/or damage. Insert an extra spark plug into the transformer and check for spring pressure of terminal (4).
The extension can be scratched and damaged with a wire brush. Do not use a wire brush on the extension.
Clean any deposits from the inside of the extension. Use a 6V-7093 Brush with isopropyl alcohol.

Measure the primary circuit by checking the voltage of the diode.
Set the multimeter to the diode scale. Connect the multimeter leads to terminals (7, 8) of the 2-pin connector. The polarity of the leads is not important. Measure the voltage between the terminals. Record the measurement.
Reverse the multimeter leads. Measure the voltage between the terminals again. Record the measurement. One of the voltage measurements is approximately 0.450 VDC. The other measurement indicates an open circuit.
Measure the resistance of the secondary circuit.
Set the multimeter to the 40,000 Ohm scale. Measure the resistance between screw (1) for the ground spring and terminal (4) for the spark plug. Note: The resistance of the secondary coil will vary with the temperature. Illustrations 3 and 4 demonstrate the relationship between the secondary coil's resistance and the temperature. A reading that is within 1000 ohms is acceptable.Illustration 3 is a graph for the resistance of the following transformers: 199-9011 and 229-9753Illustration 4 is a graph for the resistance of the following transformers: 232-6350 and 259-2078

Switch the suspect transformer with a transformer from a different cylinder that is known to be good. Install the transformers. Install the valve covers.
Switch the suspect transformer with a transformer that is known to be OK from a different cylinder. Install the transformers. Install the valve covers.
Reset the control system. Clear any logged diagnostic codes.
Start the engine and operate the engine in order to generate a diagnostic code. If the problem follows the transformer, replace the transformer. Make sure that you use the correct transformer for the engine. Reset the control system. Clear any logged diagnostic codes.If the problem stays with the cylinder, there is a problem with the spark plug or the electrical circuit for the transformer.For troubleshooting of the electrical circuit, refer to the Troubleshooting Manual.Spark Plug
If a diagnostic code is generated for the ignition transformer's secondary circuit, the spark plug may need to be replaced. Misfire and a cold cylinder are other indications of a worn spark plug. Use Cat ET to monitor the exhaust port temperatures in order to locate a cold cylinder.The service life of the spark plugs is affected by fouling due to deposits from the oil and by peak voltage. Maintenance of the ignition system is also affected by voltage. Higher voltage is required by higher inlet manifold air pressure, a higher compression ratio, or retardation of the timing. Higher voltage reduces the service life of components such as spark plugs, wires, and transformers.To help predict the spark plug's service life, use Cat ET to monitor the secondary voltage. The value is expressed as a percent of secondary voltage. The value increases as the spark plug gap wears over time. A new spark plug is at 0 percent. A value over 90 percent may require maintenance. A spark plug at 100 percent requires replacement. Maintaining a log of this voltage at a particular site will help to determine the proper interval for replacement of the spark plugs.For instructions on inspection and replacement of the spark plug, refer to the engine's Operation and Maintenance Manual. For more information on the spark plug, refer to the engine's Specifications manual.
